I have made some progress with the shadow cams. They are selectable in the Camera list. I have found that if you rename your lights, the names of the shadow cams remain the same as they were, so if you have 3 lights, and you renamed them, then added a 4th, the new light would be Light1, and the sc light would be shadow cam 4. That little characteristic had me confused at first. This new knowledge is solving a nagging problem for me. I intend to experiment with these and master them. I never used them because I was under the false impression that they were for checking the lights' aim. thanks for the info - the more I know, the faster I progress! -fritz
